TCE(trichloroethylene)으로 부터 클로로벤젠과 클로로폐놀의 생성특성

초록

The objective of this study was to evaluate the formation characteristics of CBs and CPs from TCE, aliphaticcompound. The experiment was carried out in a fixed reactor during 30 min under the oxidation condition at therange of temperature, 300~ 700C. MSWI fly ash was used as catalyst in this study. Total amount of CBs formedgreater magnitude than that of CPs overall range of reaction temperature. It is proposed that the formation of CPswas caused from hydroxylation of CBs. According to increasing temperature to 600C, the yield of CBs and CPsincreased but significantly decreased at 700C. It is suggested that decomposition rate was faster than formationrate at the high temperature. In the homologue distribution of CBs, DCBs were major products at 300C and theamount of higher chlorinated compound increased to 600C. Because they were formed by chlorination of lowerchlorinated compounds. In case of CPs, the amount of DCPs was 90% of total amounts in both thermal formationand catalytic reaction. On the other hand it was clearly observed that the chlorination rate in catalytic reaction washigher than in thermal formation with TCE only.
